Title: Add new parse case for Persons + parse 'at' and 'AT'

New case considered :
'firstname.lastname at domain.com (Firstname Lastname)'

Moreover, simple anti-spam technique (where @ becomes at or AT) is
recognized just like a @

This case happened on the official sup mailing list (http://rubyforge.org/pipermail/sup-talk/)
